Amongst the following fractions, the largest and second largest fractions, respectively are $\frac{5}{6}$, $\frac{3}{4}$, $\frac{1}{2}$, $\frac{2}{3}$, $\frac{3}{5}$

The correct answer is $\frac{5}{6}$ and $\frac{3}{4}$.

To find the largest and second largest fractions among the given set, we can convert each fraction into its decimal form or compare them by finding a common denominator.

Let's convert each fraction to its equivalent decimal value:

1. $\frac{5}{6}$ ≈ 0.833

2. $\frac{3}{4}$ = 0.75

3. $\frac{1}{2}$ = 0.5

4. $\frac{2}{3}$ ≈ 0.667

5. $\frac{3}{5}$ = 0.6

Now, let's arrange the fractions in descending order (from largest to smallest) based on their decimal values:

$\frac{5}{6}$ (0.833) > $\frac{3}{4}$ (0.75) > $\frac{2}{3}$ (0.667) > $\frac{3}{5}$ (0.6) > $\frac{1}{2}$ (0.5)

From the ordered list, we can clearly see that:

- The largest fraction is $\frac{5}{6}$.

- The second largest fraction is $\frac{3}{4}$.

Therefore, the largest and second largest fractions, respectively, are $\frac{5}{6}$ and $\frac{3}{4}$.
